Bajos de Haina, Dominican Republic presents a very favorable location for year-round solar energy generation. This tropical location benefits from consistent sunlight throughout most of the year, with seasonal variations characterized more by wet and dry periods rather than the dramatic temperature changes seen in temperate climates.
Solar Energy Production Performance
The solar energy output data shows strong performance across all seasons, with spring delivering the highest production at 6.89 kWh per day per kW of installed solar capacity. Summer follows closely at 6.65 kWh/day, making these the optimal months for solar generation. Even during the lower-performing seasons, autumn still produces 5.90 kWh/day and winter generates 5.38 kWh/day per kW installed. For maximum year-round energy production, solar panels should be installed at a fixed tilt angle of 17 degrees facing south. This optimal angle is calculated by analyzing daily solar elevation angles throughout the year and weighting them according to solar irradiance data to maximize total annual output.Environmental and Weather Challenges
Several significant factors in this tropical Caribbean location can impact solar energy production and require careful consideration during installation: Hurricane and Tropical Storm Risk The Dominican Republic lies within the Atlantic hurricane belt, with the hurricane season typically running from June through November. These powerful storms bring destructive winds that can severely damage or destroy solar installations if not properly secured. Heavy Rainfall and Flooding The wet season brings intense tropical downpours that can cause flooding and water damage to electrical components. Prolonged cloud cover during heavy rain periods also reduces solar output temporarily. High Humidity and Corrosion The consistently high humidity levels in this tropical climate accelerate corrosion of metal components and can degrade electrical connections over time, reducing system efficiency and lifespan. Dust and Particulate Accumulation Dust, salt spray from the nearby coast, and organic debris can accumulate on solar panels, creating a film that blocks sunlight and reduces energy production.Preventative Installation Measures
To maximize energy production and system longevity in this environment, several protective measures should be implemented:- Hurricane-resistant mounting systems - Use reinforced mounting structures designed to withstand high winds, with proper engineering calculations for local wind loads
- Elevated installations - Mount systems well above potential flood levels and ensure proper drainage around ground-mounted arrays
- Marine-grade components - Select corrosion-resistant materials including stainless steel hardware, aluminum frames with protective coatings, and weatherproof electrical enclosures
- Enhanced sealing - Use superior weatherproofing for all electrical connections and junction boxes to prevent moisture infiltration
- Easy cleaning access - Design installations to allow regular panel cleaning and maintenance to remove dust and debris accumulation
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Bajos De Haina
Seasonal solar PV output for Latitude: 18.4193, Longitude: -70.0407 (Bajos De Haina, Dominican Republic), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
 
Ideally tilt fixed solar panels 17° South in Bajos De Haina, Dominican Republic
To maximize your solar PV system's energy output in Bajos De Haina, Dominican Republic (Lat/Long 18.4193, -70.0407) throughout the year, you should tilt your panels at an angle of 17° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Bajos De Haina, Dominican Republic
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Bajos De Haina, Dominican Republic. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 17° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 2° South in Summer | 24° South in Autumn | 34° South in Winter | 12° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

Topography for solar PV around Bajos De Haina, Dominican Republic
Topographical Features of Bajos de Haina
Bajos de Haina sits in the southern coastal region of the Dominican Republic, positioned on relatively flat terrain that extends from the Caribbean Sea inland toward the central mountain ranges. The immediate area around this industrial town is characterized by low-lying plains and gentle rolling hills that rarely exceed 100 meters in elevation. The landscape consists primarily of coastal lowlands that have been shaped by centuries of sediment deposits from nearby rivers and streams flowing down from the interior highlands. The terrain gradually rises as it moves northward from the coast, transitioning from the flat coastal strip into undulating hills covered with a mix of agricultural land, scattered vegetation, and developed areas. The soil composition in this region is generally well-drained, consisting of alluvial deposits mixed with limestone-derived materials that are common throughout much of the Dominican Republic's southern coastal zone. Several small rivers and seasonal waterways cross the landscape, creating minor valleys and depressions in the otherwise relatively uniform topography. These water features have carved gentle channels through the terrain but do not create significant elevation changes or steep gradients that would complicate large-scale development projects.Optimal Areas for Large-Scale Solar Development
The most suitable locations for major solar photovoltaic installations would be found on the expansive flat to gently sloping areas that extend both east and west of Bajos de Haina along the coastal plain. These areas offer several advantages including minimal grading requirements, excellent accessibility for construction equipment and maintenance vehicles, and proximity to existing electrical infrastructure that serves the industrial facilities in the region. The agricultural lands situated on the slight elevation rises approximately 5 to 15 kilometers inland from the coast present particularly attractive opportunities for solar development. These locations benefit from consistent terrain that would minimize earthwork costs while providing natural drainage to prevent water accumulation during the rainy season. The gentle slopes in these areas, typically ranging from 1 to 3 degrees, are ideal for optimizing panel orientation without requiring complex mounting systems. Areas to the northeast of Bajos de Haina, where the coastal plain begins its gradual transition toward the foothills, offer large contiguous parcels of land with favorable topographical conditions. The terrain in this direction remains relatively flat for several kilometers before encountering steeper slopes, providing ample space for utility-scale solar installations while maintaining reasonable distances from population centers and existing infrastructure. The western approach from Bajos de Haina also presents excellent potential, with extensive flat areas that stretch toward neighboring communities. This region benefits from well-established road networks and proximity to transmission lines that could facilitate grid connection for large solar projects. The topography remains consistently favorable across significant distances, allowing for the development of multiple large-scale installations or single massive solar farms spanning several square kilometers.Dominican Republic solar PV Stats as a country
